This was an interesting problem, please let me know of any additional updates you make so I can add your changes to my code snippets.

EventInfo []events = ktfaType.GetEvents();
for(int i = 0; i<events.Length; ++i)
{
    MethodInfo methodInfoType = events[i].EventHandlerType.GetMethod("Invoke");
    ParameterInfo []parameters = methodInfoType.GetParameters();
    for (int j = 0; j<parameters.Length; ++j)
    {
       Console.WriteLine(paramaters[j].ParameterType + " " + parameters[j].Name);
    }
